Title: A method for grouping 802.11 stations into authorized service sets to differentiate network access and services
Inventor: YANG SHEAUSONG
IPC: H04B5/00
Filed: 2003-07-24
Abstract: A method for associating a WSTA to a service set, wherein the service set is configurable at the AP. Each service set is an arbitrary grouping of one or more network service parameters, and is typically configured for either VLAN or proxy mobile IP host. When a wireless station desires to associate with a n access point, the wireless station sends a message to the access point, the message containing a SSID. The access point then matches the SSID to a servi ce set and associates the WSTA to either a home subnet or a VLAN based on the SSID. By locally configuring the service set, the defaut VLAN and home subne t for a WSTA may be different at each AP the WSTA encounters. A security serve r is configured with a list of allowed SSIDs for each wireless station to prevent unauthorized access to a VLAN or home subnet.

Title: Drug reaction early warning system
Inventor: SPERER BEN
IPC: G06Q50/22
Filed: 2006-03-15
Abstract: The ADVERSE DRUG REACTION EARLY WARNING SYSTEM (DREW) alerts pharmaceutical companies of potentially dangerous side effects before they manifest. DREW uses biomarkers in blood and urine as well as symptoms gathered from patients taking a particular medication. It analyses and interprets this data to detect deviations from normal biological values. If found, deviations are applied to a computerized grid of early warning biomarkers to trace a pattern of developing side effects. The alerted pharmaceutical company can now take preventive action. Thus, DREW is a definite innovation from existing adverse effect surveillance systems which are activated by reported side effects. DREW attempts to prevent the manifestation of full blown side effects before they occur. The system is implemented by a network of participating physicians strategically positioned in areas where the particular medication is used.  DREW will make drugs safer for patients and limit liability from adverse effect consequences.

Title: Improved frequency-domain error concealment
Inventor: TALEB ANISSE
IPC: H04N19/895
Filed: 2004-12-15
Abstract: The invention concerns a frequency-domain error concealment technique for information that is represented, on a frame-by-frame basis, by coding coefficients. The basic idea is to conceal an erroneous coding coefficient by exploiting coding coefficient correlation in both time and frequency. The technique is applicable to any information, such as audio, video and image data, that is compressed into coding coefficients and transmitted under adverse channel conditions. The error concealment technique proposed by the invention has the clear advantage of exploiting the redundancy of the original information signal in time as well as frequency. For example, this offers the possibility to exploit redundancy between frames (inter-frame) as well as within frames (intra-frame). The use of coding coefficients from the same frame as the erroneous coding coefficient is sometimes referred to as intra-frame coefficient correlation and it is a special case of the more general frequency correlation.

Title: Diffraction grating-based encoded articles for multiplexed experiments
Inventor: TROUNSTINE MARY CATHERINE
IPC: G01N15/14
Filed: 2004-11-15
Abstract: The present invention provides methods and compositions directed toward assays of a broad range of analytes using specific targeting chemicals that bind to the analytes. The assays are founded on the use of coded assay articles to which the targeting chemicals are attached. Additionally the codes are such that they are interrogated and determined in real time. The target is analyzed as to identity, presence and quantity in real time. The methods and compositions of the invention are highly suitable for use in high-complexity multiplexed assay systems. All the methods and compositions are based on assay article that includes an optical substrate to which the chemical is bound, and in which is disposed at least one diffraction grating. The grating provides an output optical signal when illuminated by an incident light signal which is indicative of the code in the substrate. In general, coded assay article or sets thereof are employed in assay methods, including multiplexed assay methods, according to which a sample is contacted with an article or a set, and any analytes that bind to the attached chemical are identified according to the code, detected and/or quantitated.

Title: Methods and materials for assessing prostate cancer therapies
Inventor: SAWYERS CHARLES L
IPC: C12Q1/68
Filed: 2004-12-16
Abstract: Using microarray-based profiling of isogenic prostate cancer xenograft models, we found that a modest (2-5 fold) increase in androgen receptor (AR) mRNA was the only expression change consistently associated with developing resistance to antiandrogen therapy. Increased levels of AR confer resistance to anti-androgens by amplifying signal output from low levels of residual ligand and altering the normal response to antagonists. This invention provides cell based assays for use in the examination of new therapeutic modalities and provides insight toward the design of novel antiandrogens.

Title: Culturing human embryonic stem cells
Inventor: THOMSON JAMES A
IPC: C12N5/02
Filed: 2005-09-08
Abstract: Previous methods for culturing human embryonic stem cells have required either fibroblast feeder cells or a medium, which has been exposed to fibroblast feeder cells in order to maintain the stem cells in an undifferentiated state.  It has now been found that if high levels of fibroblast growth factor are used in a medium with gamma amino butyric acid, pipecholic acid, lithium and lipids, the stem cells will remain undifferentiated indefinitely through multiple passages, even without feeder cells or conditioned medium. A  humanized matrix of human proteins can be used as a basement matrix to culture the cells. New lines of human embryonic stem cells made using these culture conditions, the medium and the matrix, will never have been exposed to animal cells, animal products, feeder cells or conditioned medium.
